Because of their flexibility and reprogrammability, FPGAs have been proposed for many uses in avionics. Existing commercial FPGAs, being fine-grained, are programmable at the bit level, allowing them to be used across a wide range of applications. Compared to an ASIC developed for a specific application, however, such a fine-grained FPGA consumes more power and exhibits higher latency and/or lower throughput. In this paper we describe RADAR - a coarse-grained, programmable, radiation-hardened array that exhibits power and throughput similar to ASICs, yet contains a high degree of programmability. Containing multipliers, adders, SRAMs and a programmable interconnect, RADAR is customized to the DSP domain and targets applications that require low power and high throughput. The degree of radiation hardening in RADAR is a programmable feature, allowing a tradeoff between radiation hardness, throughput, andpower.
